tion of iodide of starch ; and an intermediate circle between 

 the heart and the exterior blue-coloured zone. This shows 

 distinctly that starch does not exist in the heart nor in the 

 layers next to it, but that it is all deposited in the external 

 layers of the root." 



" On further examination of these three sections of the root, 

 I have also found that the intermediate layers contain much 

 more proteine compounds than either the heart or the outer 

 layer where the starch is deposited. The intermediate portions 

 between the heart and the outer layers, indeed, contained, in 

 this instance, one-half more flesh-forming constituents than 

 the other portions of the root, as will be seen from the follow- 

 ing determinations :

The parsnips employed in the foregoing analyses by Voelcker

 but by no means deep. 



Prangos pabularia, a herbaceous plant inhabiting the arid 

 plains of southern Tartary, has a great reputation as a sheep- 

 food, which Dr Lindley says it appears not to deserve. 



Petroselinum sativum (formerly Apium petrosdinum) , pars- 

 ley. Parsley is a biennial plant, said to be a native of Sardinia. 

 The varieties are the common, the curled-leaved, and the Ham- 

 burg, the last of which is cultivated for the sake of its tube- 

 rous roots. The curled-leaved is the most ornamental, and it 

 possesses the advantage of being readily distinguished from 

 the poisonous jEihusa cynapium, fool's-parsley, which does 

 considerably resemble the common parsley. The tuberous
